World Chicken Festival: Sunnyside Up
Welcome to “Sunnyside Up.” This interactive opens to a word problem, a shopping list, and a menu featuring
food items.
If you click on the “Help” button, you will see that
the ultimate goals of this interactive are to un-ghost
the food images and complete the shopping list.
Click on one of the four menu items to begin your
calculations.
“Check Answers” will reveal whether your answers
are correct. There is a small margin of errors in some
of the questions, since you might come up with
slightly different answers. The exact answer will
pop up in place of your approximate answer.
For the biscuit recipe conversion chart, hitting the
“Check Answers” button will indicate (by color)
if your answers are correct (green) or incorrect (red).
